Question

A total charge of 100. coulombs flows past a fixed point in a circuit every 500. seconds. What is the current at this point in the circuit?

Answer 1

Answer:

0.200 A

Explanation:

Current is the rate of change of charge, or Coulombs per second.

I = Q/t

I = (100. C) / (500. s)

I = 0.200 A

Answer 2

The current at the given point is 0.2 A at the time 500 s when the charge is 100 C.

What is Current?

Electric current is defined as the rate of change of charge. It is measured in  Coulombs per second.

$I = \dfrac Qt$

Where,

$I$ - current

$Q$ - charge = 100 C

$t$- time = 500 s

Put the values in the formula,

$I = \dfrac {100. \rm \ C}{500\rm \ s}\\\\I = 0.200\rm \ A$

Therefore, the current at the given point is 0.2 A.
